None.FIELD OF THE INVENTION
The invention disclosed broadly relates to the field of tracking technology and more particularly relates to the field of real-time tracking through the use of loyalty cards.BACKGROUND OF THE INVENTION
A loyalty card, also known as a rewards card, points card, discount card, or club card, is an identifier that identifies the card holder as a member of a commercial incentives program. The identifier generally follows the form factor of a credit card-sized plastic card. Loyalty cards may be used in hotels, stores, clubs, airlines, and many other establishments desirous of tracking their customer/client base. In the case of a hotel loyalty card program, the card may be read in the lobby of the hotel, in order for the hotel to be advised that a specific client/hotel guest has arrived.
Known loyalty cards typically employ a scannable barcode or magstripe on the back of the card. The back of the card is scanned in order to authenticate the identity of the consumer and/or the transaction. Small keyring cards are often used for convenience. A retail establishment or a retail group may issue a loyalty card to a consumer who can then use it as a form of identification when dealing with that retailer. By presenting the card, the purchaser is typically entitled to either a discount on the current purchase, or an allotment of points that can be used for future purchases.
Typically, the card issuer requests or requires customers seeking the issuance of a loyalty card to provide a minimal amount of identifying or demographic data, such as name and address. Application forms usually entail agreements by the store concerning customer privacy, typically non-disclosure (by the store) of non-aggregate data about customers. Where a customer has provided sufficient identifying information, the loyalty card may also be used to access such information to expedite verification during receipt of checks or dispensing of medical prescription preparations, or for other membership privileges (e.g., access to a club lounge in airports, using a frequent flyer card).
It is also highly likely that consumer purchases are tracked and analyzed towards more efficient marketing and advertising (in fact one of the purposes of the loyalty card). There also remains the possibility that law enforcement agencies could be granted access to the stored information during an investigation of a customer's activities. For example, in 2004, a Winn-Dixie key-ring card was left behind at the scene of the crime, which led police to the perpetrator of the crime.
In the U.S., several major supermarket chains and at least one major pharmacy require the cards in order for customers to receive the advertised loyalty price. These include Kroger and Safeway (each through both their own name and many of their regional chain names), Albertsons, Winn Dixie, Harris Teeter, Ingles, Giant Eagle, Tops, and CVS/pharmacy. Some have tie-ins with airline frequent flyer programs, and some agree to donate a percentage of sales to a designated charity.
The practice is also common among book and music retailers, from large chains to independent retailers. In some instances, the customer purchases the card and receives a percentage discount on all purchases for a period of time (often one year), while in other instances, a customer receives a one-time percentage discount upon reaching a specified purchase level. (For example, a bookseller's loyalty card program might provide a customer with a 10% off coupon once the customer has spent $200.00 at the bookseller.) Best Buy's loyalty program similarly offers points redeemable for dollar-amount discounts after accumulating a set number of points along with other discounts from time to time, though the card is not required to receive their advertised price in most cases. In addition, office supply retailers Staples, Inc. and Office Depot started issuing club cards in 2005.
Almost all of the major hotel chains (Best Western, Choice Hotels, Holiday Inn, Marriott, Super 8 Motels, etc.) have similar cards that allow guests to earn either points (redeemable for discounts, future stays or other prizes) or airline miles (Hilton's HHonors program allows guests to earn both points and miles on the same stay, the only program to date that does so). All major US Airlines also offer rewards credit cards. Two major petrol distributors have adopted the Exxon-Mobil Speedpass which is not only a loyalty token, but also contains a mechanism for authorizing electronic payment, used by over seven million customers worldwide (in 2004).SUMMARY OF THE INVENTION
Briefly, we describe a networked card for identifying and tracking animate and inanimate objects and personnel, the card including: a radio frequency modem operable at a low radio frequency not exceeding one megahertz, the modem including a full duplex transmitter and receiver; a loop antenna operatively coupled with the radio frequency modem, the antenna operable within a range of hundreds of feet; a programmable microprocessor operatively coupled with the radio frequency modem and fully programmable within a network; a memory operatively coupled with the programmable microprocessor, the memory holding identification data; and a battery for providing power to the microprocessor.
To describe the foregoing and other exemplary purposes, aspects, and advantages, we use the following detailed description of an exemplary embodiment of the invention with reference to the drawings, in which:
While the invention as claimed can be modified into alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the drawings and detailed description thereof are not intended to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the scope of the present invention.DETAILED DESCRIPTION
We describe a networked loyalty card for operating at a low frequency, useful for identifying animate and inanimate objects and individuals. The networked loyalty card is based on the IEEE P1902.1 protocol that has significant advantages over known tracking cards using RFID technology. With the networked loyalty card, a hotel guest can enter a hotel lobby with the card in his/her wallet and by the time the guest reaches the front desk the hotel has already identified the guest and begun the check-in process. This is possible because the networked loyalty card can be read through a person, or a wallet or handbag. The card, using the P1902.1 protocol and a standard antenna, can be detected from fifty feet away and in any direction. The card does not have to be pointed in the direction of the card reader. With a larger antenna, the card signal can be detected from any direction within a one-hundred foot range. Additionally, the card is able to store much more data than known loyalty cards using RFID technology. The networked loyalty card can store upwards of 1,000 bytes.
Additionally, according to an embodiment of the present invention, specific preferences can be highlighted relating to that hotel guest (e.g. preferences for: wake up calls, restaurant bookings, room service, table seating).
Pop-up windows may be used as part of the hotel management software to alert the concierge or hotel staff that the guest has arrived at the hotel. Other areas or regions within or external to the hotel (such as a pool area or tennis area) may be similarly equipped with volume read loop antennas according to the present invention.
The loyalty card 100 uses a low frequency (not exceeding 1 megahertz, and typically under 300 KHz) and a base station design that uses large loop antennas (such as 10×10 feet to 500×500 feet). It transmits a digital ID to selectively activate a signal within the effective range of a volume read loop antenna. We use both a simple polled protocol as well as on-demand communications from the card 100.
Each such card 100 uses a full duplex transmitter and receiver (transceiver), as opposed to a transponder design used in RFID tags and RF Tags. In addition, these Networked RF Cards (NRF Cards) have significantly reduced power consumption, and long range (1000 sq feet to 10,000 sq feet per antenna), have the power capacity to add displays (e.g. LCD) and light emitting diodes (LED's) and detectors, and buttons so they may become fully interactive “card clients” (this is not possible with a transponder). These low frequencies are generally understood to have very short range (inches), have the disadvantage of limited transmission speed, but have the distinct advantage of operating in harsh environments with reduced interference (see Mar. 19, 2003 RFID Journal “Goodyear Opts for 125 KHz Tire Tag”). However, the range problem is solved by using full duplex communications and a base station with large loop antennas; moreover, the communication speed is not a serious issue in any of the expected applications.
Low frequencies make it possible to use low speed low-power integrated circuits. These integrated circuits may be fabricated using 4 micron CMOS (complementary metal oxide semiconductor) for only 10 to 20 cents and use a standard flat (quarter size) alkaline battery or a lithium battery. The small size makes it ideal for use in a credit card form factor. The low frequencies provide extremely low power consumption and make it possible to leave the receiver on at all times, drive an LCD display at all times, transmit back to the base station as many as 100,000 times, yet the card 100 enjoys a lifetime of a minimum five years to a maximum 20 years (lithium battery).
The loop antennas have the advantage of communication to modules only contained within the loop, or depending upon the communications mode (AM of FM, or PM) up to one diameter away from the loop. This also makes it possible to estimate the location of an item down to the size of the loop approximately. These non-transponder NRF Cards are novel identification cards which have the ability to transmit and receive in the manner of any radio device and do not depend upon reflection of reader signals.
The cards have a range of hundreds of feet, and have a long battery life (e.g. 10 years) with miniature button batteries, and only one or two active components. They can do this because they use very low frequencies (below 1 megahertz and preferably under 300 kilohertz) for both transmission and reception.
The card is low-cost with full two duplex way transmission and reception, can be fully programmable within the network, and as many as 10,000 or more can all function within a network as clients, with a ten to fifteen year battery life. This card 100 may be equipped with an optional LCD display 120. These cards fit easily in a wallet and can also be easily attached to a file or container using tape or other adhesive means.
Optionally, a hole 115 can be provided for securing the card 100 to a lanyard or keychain. Thus the card may be used by an individual as identification or used in conjunction with shipping data to store other shipping information such as addresses, freight contents, weight size, and shipping IDs with full programmable features.
The card 100 has additional unique features including the optional LCD display 120 as well as optional light emitting diodes (LED) 130. The LED's 130 may be different colors. The display 120 can be used to show a membership status or other identifying information.
The card 100 may also have several buttons 140 placed on its face that can be used to confirm any action associated with a transaction, or to scroll information contained in the card on the LCD display 120. In addition the card 100 may be read as it passes through a “reading tunnel,” on a conveyor and/or automatically sorted, similar to systems now based on barcodes. A single large loop antenna, or multiple overlapping loop antennas placed either in the floor or ceiling or on shelves can be used to interrogate the cards 100, read data and status and find the approximate location of the customer in the store or hotel lobby. This ability to network many cards as clients within a region makes many other functions possible within the scope of the invention.
Cards 100 may also be introduced that have no LCD display 120, no buttons 140 and 160 and no LEDs 130, at a reduced cost. These inexpensive cards may be used simply to identify the card holder and/or the card holder's loyalty agreement.
Another unique feature of this system is its ability to be programmed within a network, providing the server knows the ID of the loyalty card holder, or by a very low-cost hand-held device, in the store, club, or hotel. A card 100 can be programmed at the receiver's site with no knowledge of the card's ID. An Ethernet-enabled router can be used to manage the network, which lets users view each card 100 and its corresponding data over the Web. Users can use special monitoring software to view the data, or, when they properly configure the cards and the network, they can view the data on almost any search engine and, in some cases, the card 100 could serve as a reader, too.
The hand-held and card communication range may be easily controlled to a few inches or even a few feet depending upon the size of the loop antenna used for communication contained in the handheld, as well as power supplied to the antennas. This provides the ability for an individual to walk up to a customer with the hand-held, and interrogate the card ID status, or reprogram the card 100, or carry out any other maintenance function without any prior knowledge of the ID number or any other data that may be contained in a separate database—it is done based simply by locating the physical card 100. These features will undoubtedly be limited to specific individuals with the authority to make such changes; however this ability makes maintenance in support of the cards low-cost and allows for on-the-spot maintenance on the floor.
A final advantage of this system is its ability to transmit to a base station, independent of the base station interrogating the card 100—on-demand card transmission. This makes it possible for the card holder to send an alarm condition to the base station. The base station can be as small as the card 100 itself and can connect via a USB to a personal computer and execute commands for communicating to multiple cards in its range (in this example, approximately a 24-foot radius). The base station is a two-way transceiver for communicating with the cards 100.Communications Protocol
Each loyalty card 100 may have many IDs programmed into its memory. When manufactured all cards have the same master ID, typically 00000000. The handheld or a special programming device (a base station) connected to a computer with limited range, sends out this unique master ID. The card has an always-on receiver and reads the transmitted ID, it compares this with the IDs contained in its memory and if it finds a match, transmits a signal containing the transmitted ID back to the transmitter, indicating that it is now full open to handle communication. The base station, may then provide the loyalty card 100 with one or more unique ID numbers which may simply be a unique customer number, or other unique ID, as well as any information it may require to function. The card 100 is also provided with several random numbers stored in its memory that can be used to delay un-solicited transmissions to the base station to minimize likelihood of collisions.
The loyalty card 100 may also initiate communication, by transmitting its ID to a base station. This could be in response to a button push or in response to an event such as a transaction or loyalty membership upgrade. In the rare case when two cards simultaneously transmit, the IDs will be non-readable and the base station will send out a signal indicating an error has occurred. Two possible protocols may be initiated. The cards may be instructed to re-transmit, using a random delay stored in each card's memory register, to eliminate the overlap. Alternatively, that server may simply poll all cards in the field, one-by-one, until it locates the two cards that transmitted the signals.
Volume Read Loop Antennas
In many cases the antenna 17 may simply be wrapped around large steel shelves and the cards will all be contained within the inductive low-frequency field. The loop antennas 17 can be up to several hundred feet around. However, as they get larger, the ability to detect individual card 100 decreases, and the power required to transmit to the card increases.
Low-frequency communication has relatively low noise with antennas 17 in the range of 100 feet by 100 hundred feet, however at 500 feet by 500 feet they begin to detect thunderstorms occurring at a distance—often within 4 or 500 miles away from the antenna 17. Thus, the optimal size for these antennas 17 is on the order of about 100 by 100 feet. However, many such antennas 17 can be placed within a hotel or store to create a checkerboard array for communication to any point. This also makes it possible to localize a specific card 100 within a large hotel at least within the distance of an antenna square. A single base station 18 can be used to connect to all such antennas 17 by time division multiplexing, or the like.
The antenna 17 is connected to a base station 18 which in turn is operatively connected to a server 19 or other computer controlling mechanism; thus enabling information transmitted from the card 100 to be read via the Internet. The base station 18 is able to transmit and receive at much higher power than the card 100, but as long as the cards are contained within a loop 17, base station 18 can identify and talk to each card individually. The optimal protocol for this network is for the base station 18 to address the card 100 based on a known ID. In other words, the optimal protocol requires that the server 19 have a database of IDs found in the loop antenna 17 when using networks of cards 100. As will be understood, for addressing of an individual card 100 from the internet, the card 100 may be provided with an IP address.
Note that a handheld reader is just one format for reading the card 100. The card may be read by any data processing system configured to read signals transmitted by the card 100. Software applications can process the information on the card 100 in conjunction with information stored in the computer or accessed via a data storage device and/or the Internet to provide optimal use of the card 100. Those with knowledge in the art will appreciate the myriad of applications and uses that are possible with the loyalty card 100 and a data processing device configured to operate with the card 100.Loyalty Card As Identification Card
The loyalty cards may also be used to identify and monitor individuals (customers, hotel guests, club guests) to allow entry into restricted areas by using the same basic systems described above, and track the individuals within the buildings as they move from place to place. The face of the card 100 in this case may contain a picture ID, and the back could retain the button array 160. At critical entry points the user may, for example, be required to enter in a PIN number using buttons on the card 100 as his positive identification.
Energy source 1160, which is operable for activating transceiver 1130 and data processor 1150, may be a rechargeable battery with a pair of connectors 1165 which can be used to charge the battery. Alternatively, the energy source 1160 is selected from a long-life replaceable battery, a solar cell, a pair of electrical connectors connectable to a mating pair connectors extending to a power supply, and a tag energization antenna operable to receive radio frequency energy from an ambient radio frequency field of a second radio frequency.
Advantageously, data storage device 1140 can store a temporal history of data queries that have been received by the passport P 1100. Moreover, data processor 1150 may be programmed to cause transceiver 1130 to automatically transmit this temporal history at the low radio frequency upon receipt by transceiver 1130 of a data signal that corresponds to the identification data stored at data storage device 1140.
